... experience. Any advice? Apart from stop worrying!! After two major operations since April on my colon i take alot of pain killers. Dihydrocodeine 120mg slow release 8 a day and oramorph 300ml weekly (43ml daily). Zopiclone 7.5 to sleep. I suffer from depression and want to kill two birds with one stone, stop smoking and help my moods. Any advice? Thanks, Michael
